Headless Linux client setup
You can compile the Linux client without the GUI component by using
./configure --enable-headlesswhen compiling.
Once installed and running you can configure the Linux client from the server web interface (use the default directories to debug to configure the backup paths).
Internet mode
If you want to configure the client as internet client, you need to supply the server name, port and the authkey (assuming there already is an internet client with the name `hostname`. See http://www.urbackup.org/Administration_Manual.php#x1-200006.2) via:
echo "internet_server=example.com
internet_server_port=55415
internet_authkey=foobar
internet_mode_enabled=true" > /usr/local/var/urbackup/data/settings.cfgYou can start the client via
urbackupclientbackend -i -v debugto see if it can establish the connection sucessfully.
